Overview
The LM158A MDE is a low-power dual operational amplifier manufactured by Texas Instruments. It consists of two independent, high-gain, internally frequency-compensated op amps designed for single power supply operation over a wide voltage range. The device operates from a single supply of 3V to 32V or dual supplies of ±1.5V to ±16V. Key electrical characteristics include a large DC voltage gain of 100 dB, a unity-gain bandwidth of 1 MHz, and a very low supply current drain of 500 μA that remains essentially independent of the supply voltage.
Feature Summary
- Two internally compensated operational amplifiers
- Compatible with all forms of logic
- Power drain suitable for battery operation
Applications
- Transducer amplifiers
- DC gain blocks
- Conventional op amp circuits in single power supply systems
Procurement Notes
Verify the specific radiation specification required for your application, as the LM158A MDE is available with different radiation options including High Dose Rate (100 krad(Si)) and ELDRS Free (100 krad(Si)). Confirm the exact ordering suffix matches the desired radiation tolerance and package type before procurement.
Selection Notes
Select this component when designing circuits that require direct sensing near ground and output swing to ground while operating from a single power supply. It is suitable for applications where eliminating the need for dual supplies is critical. Ensure the design accommodates the specified input common-mode voltage range which includes ground.
Part Context
This part belongs to the LM158 series of low-power dual operational amplifiers. It is specifically designated under the QML (Military Grade) product line, indicating it meets rigorous quality conformance inspection standards per Mil-Std-883. The 'MDE' suffix identifies it as a die sale item intended for custom packaging or hybrid microelectronics applications.
Replacement Considerations
Substitute with other LM158QML variants such as LM158AH or LM158AJ depending on the required radiation hardness level (High Dose Rate vs. ELDRS Free). Verify compatibility with the target substrate or packaging method if replacing a standard packaged unit with this die sale option.
